Hey all, I bought some 'vintage' poker chips a few years ago off a guy who bought them at a garage sale. I owned a poker club and he came in one day with them and I said "sure, I'll buy them" and totally forgot about them. I've tried to look them up in Google images, but can't find anything concrete about them. They are definitely faded, well used, and I'm positive they're clay. Any ideas on these?
